In addition, the next-generation transceiver now can be used in unlicensed frequency bands ranging from 779-965 MHz, which broadens the scope of operation from the previously supported North American (915 MHz) and Europe (868 MHz) bands to include China’s 779-787 MHz radio frequency spectrum.

The ZL70251 is fully functional across the industrial temperature range, while still delivering the industry’s lowest peak power at 2 mA in both transmit and receive mode. This performance enables extremely low-power wireless nodes to operate in harsh environments. It is offered in a compact 3 mm x 2 mm chip scale package (CSP) and requires only two external components, which makes it ideal for products with space constraints.

A suite of ZL70251 product development support tools are available, including an application development kit (ADK), a low-power wireless communication software code starter for point-to-point connections and wireless sensor reference designs based on coin cell batteries.


The new device is sampling now and will reach full production status in July 2013.
